Well, I think that the dude who said that the tongue was touching the external part both made of metal was the problem was right.

Maybe some dirt helped the problem...

So I cleaned it and then I gently pushed the tongue far from the side and now it works great. Thank you

EDIT: problem persists.... damnit

Just thought I would mention

I had a possibly related but different charging problem on my previous Galaxy Nexus. The screen wouldn't come on randomly, but it wouldn't connect to a PC or take a charge while the phone was on. I sent it into Samsung and they sent me back a brand new one. No problems for a few weeks, then all of a sudden this week I started getting the intermittent "ghost charging" where the charging indicator would come on when the phone wasn't plugged in, causing the screen to come on randomly.

I was just about to call Samsung to send this one in again when I tried the toothpick trick, and it has so far worked like a charm.

WORTH NOTING: Up until now, I have used entirely non-standard chargers for both Nexus' that I've owned, both which ended up with charging problems. It seems strongly indicated that this issue has to do with stress on the mini USB port, most likely due to using non-standard chargers.

I'm going to order a couple of standard samsung chargers from Amazon today and use exclusively those going forward, and fall back on the toothpick trick if I see the problem again.

Thanks for all the help on this thread, really hoping I don't have to send mine back again.
[Samsung Galaxy Nexus] killer8297:
Well the paper clip trick was short lived, my problem started again. And this time no matter how far I push, the problem keeps on coming back. I think I'm going to buy the usb circuit from ebay and see if that fixes it.
[Samsung Galaxy Nexus] lemondroid:
I have this super annoying problem as well now, after I flashed MIUI 4.0.4

When I get back to Froyo, it does not have any similar bug..

I have Galaxy S2..
[Samsung Galaxy Nexus] adeklipse:
Questions to the victims of this problem:

Did you plug in any non-Galaxy Nexus micro USBs to its port?

I'm asking because I had this problem twice, and both started because I inserted a BlackBerry microUSB cable into my Nexus.

Fixed by adjusting the pins inside the Nexus's port with a knitting needle (by pushing them up a bit).

samsung charging problems

had the exact same problem with my galax s2. didnt want to wait 5 weeks to get it repaired so i bought another. They got back to me and said they would replace the divice. i opted to get a nexus as the replaicment s2 i got had the same drop out problems as my first. since found out it was vodafone and i think my nexus sux compared to the s2.

now my nexus wont recognise it is pluged into pc or charger for the last 4 days but would still charge. it would go flat over night where as before it wouldnt loose any charge over night and know it wont charge at all. when i plug into pc it says usb divice has malfuntioned. 0 luck with samsung but when working the best phones ive ever had. so know ive had 2 x s2 and one nexus and had charging problems with all 3
[Samsung Galaxy Nexus] mietens:
this fix my issue

thank u soooooooooo muchhhhhhh i went to service station and they told me to replacement but i wasnt ready for that i was abt to sell it until i read ur post and issue is solved in less than a minute after suffering a lot of months with it.. thanx
[Samsung Galaxy Nexus] chrispix:
Mine started doing the charging issue over the weekend. And it appears it won't take a charge when it already thinks it is charging. Computer won't recognize the device either (used multiple usb cables). Since I purchased it from overseas, Samsung USA won't fix it.. They want me to ship it back to the UK to get fixed.. Guess I will just deal with the issue and order the $10.00 part on ebay, and be done with it.. What a pain...
[Samsung Galaxy Nexus] killer8297:
I finally got the USB port replacement and I have to say it was a disappointment. The bolt still appears after the replacement and it still says discharging until the battery is around 70%. The good part is that the screen stopped randomly turning on and off, so it didn't solve all the problems.
[Samsung Galaxy Nexus] krunal1981:
Yeah mate .. used a Blackberry microusb cable and the problem started. do you still have the problem after adjusting the pins inside the nexus port. i aint sure how to do this?
[Samsung Galaxy Nexus] dgwphotography:
I had to send mine in for warranty repair (ugh)

I had the issue of it showing charging while not plugged in, and the battery life was horrible because of it...
[Samsung Galaxy Nexus] jimmiegeddes:
Started having this problem last week. Constantly said it was charging. I called Verizon yesterday and was told it's a "known hardware issue" and they would be overnighting me a replacement Nexus.
[Samsung Galaxy Nexus] oneguyks:
If it's a hardware issue, why the "battery indicator" (an app in market) doesn't get confused by this hardware issue? (bent pin or whatever).

The battery indicator app always displays the correct status. i.e "discharging since 7:46 AM ..." , even though the phone builtin icon incorrectly shows "charging" even when not plugged in.
[Samsung Galaxy Nexus] marshalllaw:
Was happening to mine today. I nearly **** myself. I even contacted the place I got it from for a warranty. I tried cleaning it with a tooth pick to no avail and then I saw someone used a piece of paper to clean it. Did the job :). Hopefully the issue does not return / wasn't a manufacturing fault or else I'll need to go through the awful process of a warranty claim. It looks like the issue is just dust / crap on some part of the connector making the phone think it is charging.

p.s my phone always said it was charging but I was able to connect it to the computer and actually charge it, so my issue may be slightly different to some other peoples. Hope this helps somebody.
[Samsung Galaxy Nexus] sidmuer:
I just had this issue happen yesterday. I was all freaked out.

Thought I had a virus since it started right after a couple APP updates. Redid AOKP, deleted a bunch of apps, etc.. etc... still same issue. Would always say it was charging. Plugged in or not.

Took a micro screwdriver. The thinnest, flattest i had. Bent the usb flat piece inside the port VERY gently, and just a slight nudge. All fixed.

Seems it is directly physical hardware related. I can see this happening again. And maybe soon breaking. All because the 2 little steel sensor pins, to see that a cord is plugged in, is set TOO close to the usb contacts on each side of it. How silly!

EDIT:

More detail...

When I had the phone stuck in always charging mode. Plugged in or not, I was actually able to charge when plugged in. I don't see why it wouldn't anyways, as the usb cable has a casing barrier that separates those sensor pins from the main contactor pins.
[Samsung Galaxy Nexus] peewster:
So i had this issue since this morning, weird, but somehow it is fixed.

What i did:

remove battery

pressed and hold the on/off button for a few seconds. (unloading last power?)

charger on net power (not on the PC)

plugged the phone onto the power cord.

put the battery back in

leave it charging for an hour

boot the phone.
[Samsung Galaxy Nexus] M3TR1C:
Just noticed having this problem also. I'm gonna head to the verizon store and see what they end up telling me. This is an issue I can't tolerate.
[Samsung Galaxy Nexus] truecrisis:
Had the same issue. Went crazy trying to figure it out.

But it was a simple fix.

I took a thin knife and bent the little 4-pin plate in the USB port up by a millimeter. It was touching the bottom of the port causing a short-circuit and made the phone think it was plugged into a computer USB cable.

Havent had the issue since then, but then again I also stopped using my little USB dongle that caused the USB pins to bend down in the first place.
[Samsung Galaxy Nexus] kelkelkel:
I have had no problems while running on the CM Roms. Does this only happen on stock?
[Samsung Galaxy Nexus] krunal1981:
I am unable to root my phone . When I connect my phone to the computer it says USB device malfunctioned
[Samsung Galaxy Nexus] anoxi:
Same charging problem.

After a full charge, the phone thinks it is charging for a second, when the display try to turn off. The result is a always awake screen..

I send my phone in a repair centre, they changed the USB board.

I got my phone back, with the "newest" software, they flashed 4.0.1 which is updated from Samsung -.- Before I had a Google one. Firstly, I had to flash the Google stock Android 4.0.4.

After the first full charge since the repair, I noticed the same problem as before -.-

I love my phone, but the charging problem is a big issue..

I guess I have to send it again for repair, two more weeks without the phone

Is there anyone else with a noob repair centre?
[Samsung Galaxy Nexus] krupka:
Same problem here for about a month.

I tried this

And it has been working since.

It's been a week and still working.
[Samsung Galaxy Nexus] M3TR1C:
Just went to the verizon store and they instantly said they are sending me another one. I would say to do this if you could if they are cool with you. They are just calling it a hardware issue and it falls under the 1 year manufacturer warranty.
[Samsung Galaxy Nexus] triciopa:
Actually, mine started with this after I installed CM.
[Samsung Galaxy Nexus] blackbearblanc:
Good work. Mine has been like this for three weeks. Its half a year old.

Drains batt when screen goes on and on thinking its charging.

[Samsung Galaxy Nexus] vphilot:
I'm on SII (AT&T), and it also started 2 days after I flashed CM9 over Samsung's Gingerbread 2.3.4.

The toothpick trick seems to work temporarily for me, but anytime I plug ANY charger (even stock) the charging issue comes back over and over.

What I don't understand is that is shows charging BOTH in lock screen and battery icon, but sometimes Settings > Battery Usage seems to see the reality that it's not charging.
[Samsung Galaxy Nexus] pvkiniyan95:
nexus charge issue solved

Hey guys i got it right it seems you have issues in charge port

I solved it by a knife. Take a knife and gently insert in the charge port and push it down

The plug the usb cable it might work
[Samsung Galaxy Nexus] vphilot:
Yes it's working temporarily...

But it surely will come back and, if you're a troll like me, you'll probably do it again and break the damn connector.

Had to take my phone to a local store and they replaced the whole connector. Costed me round $40 (I know, it costs $6 on Ebay but I'm in Brazil and it would take forever to get here)
[Samsung Galaxy Nexus] asxa86:
So I have had this problem a month after I got my first nexus. Stopped charging. Stopped connecting to PC. Sent it in, got a refurb back. Had it for 2 months and then same deal. Stopped charging. Stopped connecting. Problem is I dropped the refurb the day I got it and shattered the screen so I can't return it. Bought a new phone and decided to mess with my nexus some more. Turns out there was dirt packed into the USB port. Dirt and lint from my jeans pocket. A thin pocket knife cleared it out and my phone is back to working order.
[Samsung Galaxy Nexus] blackbearblanc:
Mine has stopped working the problems. Don't know why. Charged w another charger i had.

:good: Velke dakujem. I had same issue and this help.
[Samsung Galaxy Nexus] hexinn:
So yesterday my phone died. Usb board not working anymore. Unfortunately I dont have Vodafone insurance but its still under phone warranty. So I sent it today from Vodafone store, hopefully they gonna repair it like hardware problem.I will update it later.Cheers :eek:
[Samsung Galaxy Nexus] RossJJ:
Yeah good-luck with that. I sent it off to them and they refused a warranty repair tried to charge £100 for the repair. A friend had the same issue with his SII and sent it to Samsung and they repair for £40 if out of warranty.

I've bought a new board to fit cost £10.99 on eBay.
[Samsung Galaxy Nexus] hexinn:
Did u change it by ur self ?Its hard to do it? My device has been despatched to repair center today so I will see later on. will update..
[Samsung Galaxy Nexus] lewisb246:
I think you need a new battery mate sorry to say but i think it has had it
[Samsung Galaxy Nexus] hexinn:
I tried 2 different bateries with same problem.. I got just bad luck for smartphones.:angel:
[Samsung Galaxy Nexus] gbenj:
Were you able to complete the change? I just bought a new piece to replace the USB and would appreciate any details you can give me on the replacement.

Thanks.
[Samsung Galaxy Nexus] mzxx:
This USB issue is a bit of a worry. Coming from the Nexus One power button problem I'm frankly a little annoyed that a clear hardware fault has shown up on the Galaxy Nexus. Not to mention the looming possibility of the Gnex having its own power button issue - sounds like more and more people are experiencing this...
[Samsung Galaxy Nexus] lionsson:
My GNex is dong it too.. tried all the tricks nothing seem to work. I guess I will have to call Sammy.
[Samsung Galaxy Nexus] gbenj:
By plugging it in a bunch of times I was finally able to get the computer to recognize it in Fastboot mode so I was able to flash back to stock and relock it.

Replacement coming from Verizon, so good thing i was able to get it relocked.
[Samsung Galaxy Nexus] enganear:
I just returned from my Verizon store. They said they had never heard of the always on charge indicator issue, but they are sending me a replacement phone next week.
[Samsung Galaxy Nexus] ace8707:
Mine was having the same problem. It started randomly after I had been on AOKP b40 for more than a week. I waited about 5 days and tried restoring nandroids but nothing worked. I called VZW and the tech guy they connected me with searched for it and found it in his forums or wherever he looked (sounded like he was basically just searching Verizon forums and a few common android forums). He said it was a known issues that google was aware of and working on, but this doesn't seem like an issue with Android, it seems like hardware. Regardless he was willing to replace my phone and they're sending me a warranty replacement.
[Samsung Galaxy Nexus] yungballla6:
ANSWER

Use toothpick and gently clean charging port to the phone, fixed problem for me. Removed a lot of dirt surrounding connector inside the port.
[Samsung Galaxy Nexus] therealciviczc:
I started having this issue about 1 week ago. Mine just wouldn't charge at first. I had to keep messing with the plug to get it going. Finally i read about bending the tab up and tried that, although i really couldn't find anything at work strong enough to bend it. I must have done something because that is when it started doing the flickering, or showing a charge even when it wasn't. It was at that point that I came here and read about various fixes. I tried bending the tab again and every time I'd put something in there to bend it (plastic, so non-conductive), it would stop saying charging for a second, but then go back to charging, even if the plastic was wedged between the tab and the outside of the port. At that point I thought i must not be a bent tab. I decided to try cleaning it with paper. It was pretty dusty and dirty. Part of the way through cleaning it, it stopped saying charging and has not started since. I'm almost positive it was just packed with dust. Long story short, if the tab bending doesn't do it, try cleaning it carefully, but really really well.

Also note that if you're on VZ, and less than a year in to your contract, they will overnight you a new phone if you have a problem. I know people love to hate on Verizon and for good reason sometimes, but their customer service has always been amazing for me. :good:

Charging when not plugged it

I got a gnex on craigslist yesterday and am having the same problem. I have the I515 model, will that board work for me? How difficult/what did you do to replace it?

Edit: ordered the OEM Flex Cable Charge Port for Samsung i515 Galaxy Nexus CDMA Ribbon Circuit PCB for $15. So in a week or so i should be able to replace. Strangely though doing a battery pull seems to correct the issue until the phone is plugged in again.
[Samsung Galaxy Nexus] Androidin':
Where are you guys buying your replacement parts? A quick search of ebay didn't turn up much unless I'm searching the wrong terms...?

*edit* Think I found what I'm after for my GSM Nexus:

http://www.ebay.com/itm/Original-Sa...988?pt=LH_DefaultDomain_0&hash=item20c7190084

Is that correct?
[Samsung Galaxy Nexus] Androidin':
I ordered the one I linked to. Hoping the shipping won't take too long since the seller is in Canada and so am I.

Found this guide at ifixit for the Verizon Nexus and I'm hoping the GSM Nexus is similar.

http://www.ifixit.com/Guide/Repairing-Samsung-Galaxy-Nexus-Micro-USB-Charge-Port/9641/1

Now to find some plastic prying tools locally.
[Samsung Galaxy Nexus] gbenj:
If you're looking for prying tools to take the plastic off of the backing, guitar picks work well.
[Samsung Galaxy Nexus] JediNinjafication:
Mine would do that too..only if hot tho then would power off and reboot and plug in with screen off and would charge fine. it wouldn't charge when using it,. I keep the screen all the dim. Finally fully charged and downloaded battery calibration and wiped the stats. Used "normally" whatever that is, until it had like 4% left and then charged without touching it until full. (bout killed me). Didn't even turn screen in to check progress. Haven't had issue since. Even charges while using it

Android is upgrading...
[Samsung Galaxy Nexus] Androidin':
It's strange. I've been running the stock battery down all day today and the battery info screen has always displayed info as if it is plugged in and charging (which of course it's not) but now that the battery warning messages are popping up, you can see in the battery info that while it is displaying the low battery warning, the phone believes it's on the battery instead of charging.
[Samsung Galaxy Nexus] ticholas:
Phantom Charging.

So I too am having the issue where it thinks it's charging and being plugged/unplugged causing the screen to come on and go off, thus effectively killing the battery, but once it gets to 75% it stops. I've replaced the charging flex board / charging port board pcb 2 times and to no avail. my thoughts are that it is hardware related to the "rapid charge" module on the main PCB up by the sim / memory area on the pcb (near the battery pins) i bought the phone used and am under no warranty, so i think its safe to say i'm effed.

[edit] i should also note i've done the reflash back to stock and unroot and well, basically every other software related fix that everyone else has mentioned.

[edit#2] also, i have four batteries in total, all oem, never dropped.
[Samsung Galaxy Nexus] JediNinjafication:
http://www.gottabemobile.com/2011/12/06/galaxy-nexus-nfc-feature-requires-original-oem-battery/

http://android.stackexchange.com/tags/samsung-galaxy-nexus/hot?filter=month

I can't find the one that said NOT to use non nfc batteries or charge it I another phone. Guess dropping it can affect the charge also because battery has a chip in it.

Android is upgrading...
[Samsung Galaxy Nexus] blackbearblanc:
Try shutting off nfc and androidbeam.it worked for me.

Maybe theres something with the battery, which has some nfc thing on the side of it.
[Samsung Galaxy Nexus] msalsaeed:
I had this problem tried many things. The only thing that solved is to rise the little tongue in the charging hole towards the screen.
[Samsung Galaxy Nexus] El Daddy:
Well you can add me to the jacked up usb port club. WTF...

Edit: Fixed. For now... I used a toothpick and dug out quite the clump of pocket lint. Hopefully that was the issue.
[Samsung Galaxy Nexus] Androidin':
Mine is currently at the repair depot hopefully getting fixed. I tried cleaning out the port and bending the tongue up but neither did anything to solve my charging issue.
[Samsung Galaxy Nexus] anoxi:
I can avoid the charging issue, if I remove the USB cable (stop charging) before the akku level rise over 90 %.

So I think it would be a good workaround, if there is a app, which softwarebased the charging process stops at 89%.

I couldn't find such a app, know somebody a similar app? Or is it actually possible to stop the charging process with software?
[Samsung Galaxy Nexus] Heladocaliente:
I'm having the same issue as before and I'm now on 4.1.1.

What I really don't understand is that the battery indicator in the top right corner tells me it's charging while the lock screen tells me it's discharging. It seems to me like a software problem... Anyone has the exact same issue?

P.S. Ohh and I centered the metal "tongue" in the port connected and yes when I disconnect the charging cable, the battery indicator is updated but after 5 seconds it goes back to charging state (lightning bolt).
[Samsung Galaxy Nexus] klone96:
I sat here and read all 17pages.. I have the same problem as everyone else including the OP, its funny bcuz I didn't start having problems until I upgraded to Jellybean 4.1 I obviously don't have VZ or Sprint and my phones an import from Europe.. I had to buy insurance from ENSQUARED but I'm afraid even if I get another one sent the problem maybe on going.. if this is in fact a KNOWN ISSUE I hope it gets worked out with the next GOOGLE NEXUS phone bcuz if not I'll be very disappointed.. for now I guess I'll wait for a replacement device (hopefully a white one) and hope its gets me through to the next major Nexus device.. as u can tell after 17pages if given up.. if anything I'll go back to my Nexus S or buy a international version of the SGS3/HTC ONE X
[Samsung Galaxy Nexus] Androidin':
Just got my phone back from repair and it's fixed and I hope it lasts. On the repair slip it states the work done as:

I've flashed it back to JB 4.1.1 so we'll see how it all goes. My friend at work has a GN and he hasn't had any charging issues in his 5 months of ownership and he is also rooted, unlocked, flashed with JB etc.
[Samsung Galaxy Nexus] klaidliadon:
My experience

I'm having the same problem since 10 days. At the beginnig the phone was always charging, even unplugged, and now, every now and then it behaves like it's plugged and unplugged for a fraction of second, resetting the usage time in the battery monitor.

After some days using only the original samsung usb cable the problem disappeared.

Yesterday I was forced to charge it with another cable and the problem came back again.
[Samsung Galaxy Nexus] Justhim:
I've had the same problem, started 2 months ago. It started around, or exactly, at the time I switched to the JB rom that was leaked the first day.

First I thought this was the problem so was hoping on software updates, but this all didn't help. The I arrived on some forums, including this topic, about the problem. Now everytime the problem appears, I'm lifting the 'pin' in the charge hole, with a small knife, and the problems is 'solved' for some time. 2 weeks ago I did this for the last time, and since than also only used the original cable, which I didn't before. So I guess the original cable isn't 'bending' the pin in the charging hole (that much).
[Samsung Galaxy Nexus] poolemit:
i need to replace the charging port as well but the problem is that there are significant cracks on the screen (which i do not want to replace because the phone works fine as is). question is, will this screen hold up if the phone is disassembled/assembled for the repiair? pic: http://i.imgur.com/ubebl.png
